Questions
Why does my job never run at the time I expect?
Usually the server time zone, or a missing PATH. Cron runs with a minimal environment, so commands that work in your shell can fail silently. Use absolute paths, and redirect output to a log file rather than assuming you would notice a failure.
How do I run something every 90 minutes?
You cannot express it in a single cron line, because step values must divide evenly into the field. Either use two lines covering alternating hours, or schedule hourly and have the job itself decide whether to act.
